Radiocarbon dating of prehistoric hearths in alpine northern Sweden: problems and possibilities

The chronology of prehistoric Sami settlement sites has previously been established by conventional radiocarbon dating of bulk charcoal samples associated with hearths from sunken hut floors (stállo-foundations). Here we present results of a comprehensive dating exercise of stállo-foundations in the alpine area of northern Scandinavia using Accelerator Mass Spectrometry (AMS) radiocarbon dating of charcoal. Over a 3 km² study area, AMS calibrated ages of hearth charcoal from 22 stállo-foundations across 12 sites securely date these features to between cal. AD 640 and AD 1180. Only small variations in age were found between charcoal samples from different areas of a given hearth. Statistical analysis of all the charcoal AMS radiocarbon dates obtained reveals that 12 stállo-foundations across nine sites are contemporaneous and date to the Viking Period (AD 800–AD 1050). The tightly constrained AMS-based chronology of stállo-foundations contrasts with the existing chronology based on conventional radiocarbon analysis, which places these features within a significantly greater time-frame of between AD 600 and AD 1900, with most dates ranging between AD 800 and AD 1350.This discrepancy is likely to result from the necessity of collecting composite hearth charcoal particles, which may originate from different phases of occupation, in order to achieve the required final carbon content for conventional radiocarbon analysis. We argue that the new AMS-based radiocarbon chronology of stállo-foundations presented here supersedes the existing chronology based on conventional (Gas Proportional counting) radiocarbon analysis and we advocate the use of AMS radiocarbon dating in future hearth investigations.     

Living Places or Animated Objects? Sámi Sacrificial Places with Metal Objects and Their South Scandinavian Parallels

Abstract

The article takes its point of departure in 12 Sámi sacrificial places from northern Sweden and Norway. It is argued that the sites with metal objects of the ninth to fourteenth centuries in a number of ways are comparable to acts of deposition in south Scandinavia. These Viking Age depositions consisted of partly the same types of artefacts, took place on the shores of wetlands with sacral names and were in use in the same time period as the Sámi sacrificial places. The similarities and differences between the two traditions are discussed, focusing on some possible links between aspects of animistic world views and biographical perspectives on artefacts. This opens up the possibility that not only the Sámi, but even the Old Norse world views contained elements of animistic perspectives. It is claimed that the two traditions reflect partially parallel ways of handling the landscape and dealing with objects among the Sámi of Øvre Norrland and the Norse population of south Scandinavia.     

Historians, prehistorians, and the tyranny of the historical record: Danish state formation through documents and archaeological data

Historians traditionally have viewed the emergence of Denmark as a nation-state through western European primary sources, inferring a fragmented, politically divided region between AD 800 and AD 1050. Conversely, archaeologists using local-scale, single-site data argue for unification by ca. AD 800. An alternative is offered, combiningregional-scale archaeological methods (rank-size analyses) and consideration of westernand northern European texts. This approach reveals that as disparate polities unified, the “homelands” of ruling dynasties came under control quickly, while peripheral areas remained largely autonomous. To incorporate peripheral areas, rulers manipulated the location and function of political and economic centers. Local resistance to change is reflected in slow, uneven unification, interregional elite competition, and eventually, armed rebellion. The apparent discrepancies between historic and prehistoric data are no error; in fact, they mirror the inherent conflicts of this profound social transformation.     

A Late Iron Age Boat‐Grave from Petersdal,Denmark

In 1921 a secondary grave was excavated in a Bronze Age burial‐mound on the island of Amager in the strait of Øresund between Denmark and Sweden. Recently the material was examined in detail and the result is presented here. This grave proved to be one of the few Late Iron Age boat‐graves in South Scandinavia. The boat, only preserved through a pattern of clench‐nails, was 10–12 m long. It contained traces of grave‐goods: sword, spear, riding‐gear, bucket and chest, but no trace of a body survived. The grave is contextually dated to the first half of the 8th century. © 2012 The Author     

Diatoms as bioindicators of site use: locating turf structures from the Viking Age

Diatoms recovered from archaeological features on a Viking Age farmstead excavation in the Mosfell Valley in southwestern Iceland are utilized as microscopic indicators of turf-based structures. Eroded turf can be difficult to distinguish macroscopically from naturally occurring sediments because turf foundations erode and melt into the landscape over time, leaving minimal evidence of site use. Turf was a principle building component in Iceland until the early 20th century. Turf strips and blocks were harvested from lowlands where organically rich peat and abundant water contributed to the development of bog plants with thick root mats that produced premium turf. Diatoms embedded in turf reflect the ecological conditions of the peat-bog at the time of deposition. Turf was cut from the bog and transported to higher elevations where drainage was more conducive to house construction. Siliceous diatom frustules are resistant to decay and preserve well archaeologically. The presence of diatoms in archaeological sediments is considered a marker of sediment provenience and an indication of human site use and anthropogenic modification of natural substrates. This paper demonstrates how diatom analysis can determine the presence and delimitation of archaeological features otherwise difficult to distinguish with the naked eye.     

The soils of an Iron Age farm site ‐bjellands⊘ynæ, SW Norway

Soil investigations have been carried out at an Iron Age farm site lying under natural vegetation. The soils of the area were mapped and described, and soil samples analysed for pH, organic carbon, total nitrogen, acid‐soluble phosphorus, and available sodium, potassium, calcium and magnesium. Two soil types were distinguished on the mineral soils ‐ Brown Podzolic Soils and Iron Humus Podzols. The former are associated with a higher pH, higher phosphorus contents, and a lower carbon‐nitrogen ratio. These differences arc difficult to explain by natural causes, and arc ascribed to cultivation and manuring of the soil during the occupation of the site.     

Identity, threat and defiance: interpreting the “bulwark”, a 12th century lake building on Gotland, Sweden

“Bulverket” in Gotland has been one of Sweden’s longest standing archaeological mysteries since its purpose was first pondered by Oscar Montelius in 1868. For some, the enormous timber construction in the middle of the lake at Tingstäde was obviously military, but other suggestions spanned the entire social spectrum: a market place, a religious centre, a crusader barracks, a pirate base or even a prison. Whatever its function and meanings, the enterprise demanded a prodigious investment of labour and must represent someone or some group with considerable power and motivation. Yet soon after its construction it seems to have played out its role and been abandoned. The reasons are of course implicated in the fascinating structure itself but they also have to be sought in the wider context of contemporary Gotlandic society.     

Imaging skeletal remains with ground-penetrating radar: comparative results over two graves from Viking Age and Medieval churchyards on the Stóra-Seyla farm,northern Iceland

Detailed ground-penetrating radar surveys were conducted at separate Viking Age and Medieval churchyards on the Stóra-Seyla farm in Skagafjörður, northern Iceland. Surveying over a previously unknown site (ca. AD 1000) that is located just a few meters above the Skagafjörður valley bottom delineated the remnants of a buried circular turf wall that encloses a church structure and several graves. The radar profiles over the graves contain strong hyperbolic reflections that emanated from the skeletal remains. Over one of the graves, an air-filled void within the chest cavity had been detected as noted by reflections with normal polarity which indicated a boundary towards increasing microwave velocity. During excavation, the soil surrounding an intact rib cage collapsed thus confirming the presence of the void. In general, the skeletal remains were very well preserved and yielded strong reflections which permitted the orientation of the body to be determined. Conversely, the radar profiles over a grave from a more recent churchyard (ca. AD 1200) show ground disturbance but lack hyperbolic reflections. Upon excavation, only teeth were recovered. The poor preservation of the skeletal remains is attributed to increase contact with infiltrating groundwater from an overlying gravel layer. Interpretations were aided by time-slice overlay imaging, forward modeling and analysis of the reflection coefficient.     

Marine resource intensification in Viking Age Europe: the molluscan evidence from Quoygrew,Orkney

This paper addresses whether molluscan evidence from Orkney can shed light on the hypothesis that there was a trend towards the intensification of marine resource use at the end of the first millennium AD. The stratified middens of Quoygrew, which date from approximately the 10th to the 13th centuries, are shown to contain predominantly limpets, which may have been used for baiting fish. From metrical data it is shown that these limpets reduce in size through time. In order to test whether this observation is related to intensification in exploitation, analysis of limpet shoreline location was carried out. In addition, age data were used to demonstrate a lowering of average age which suggests intensification in gathering rather than environmental influences, particularly during the 11th–12th centuries at this site.     

Valkeapää's Use of Photographs in Beaivi áhčážan: Indigenous Counter-History versus Documentation in the Age of Photography

This article examines the photographic material of the Sámi cultural mobilizer Nils-Aslak Valkeapää's Beaivi áh?á?an (The Sun, My Father), published in 1988, with theoretical perspectives from anti- and postcolonial studies. The analysis focuses on how Valkeapää's use of photographs involves that the colonial past is examined from the vantage point of the anti-colonial present of the 1980s. Valkeapää's re-contextualization of photographs from ethnographic collections assembled in the late nineteenth and early twentieth centuries in a book he called a family album of the Sámi is discussed as an example of Sámi counter-history that is part of the decolonization process. When analysed with perspectives from anti- and postcolonial studies, the documentation of the way of life of the Sámi people in the late nineteenth and early twentieth centuries exemplifies a practice which has constructed the Sámi as the others of modern society. The article discusses how the construction of the Sámi as the others of modernity is deconstructed and challenged in present-day indigenous identity politics.     

Integrated geoarchaeological methods for the determination of site activity areas: a study of a Viking Age house in Reykjavik,Iceland

For over a decade, geoarchaeological methods such as multi-element analysis and soil micromorphology have been used to identify and interpret activity areas on archaeological sites. However, these techniques, along with others such as magnetic susceptibility, loss on ignition, and microrefuse, artefact and bone distribution analyses are rarely integrated in the study of a single site, even though they provide very different and potentially complementary data. This paper presents a comparative study of a wide range of geoarchaeological methods that were applied to the floors sediments of a Viking Age house at the site of Aðalstræti 16, in central Reykjavík, Iceland, along with more traditional artefact and bone distribution analyses, and a spatial study of floor layer boundaries and features in the building. In this study, the spatial distributions of artefacts and bones could only be understood in the light of the pH distributions, and on their own they provided limited insight into the use of space in the building. Each of the sediment analyses provided unique and valuable information about possible activity areas, with soil micromorphology proving to have the greatest interpretive power on its own. However, the interpretation potential of the geochemical methods was dramatically enhanced if they were integrated into a multi-method dataset.
